2 Claims.

Various tests made have demonstrated the fact that we are able toproduce soap-like materials possessing an excellent and efiicientemulsion and cleaning power, if we bring sulphonated oils as forinstance Turkey-red-oil or other similar sulfates and sulfonatestogether with the alkaline or ammonia salts of phosphoric acid.

It is a known fact that phosphate of soda particularly the tri-sodium(phosphate, which, if brought together with water, dissociates intocaustic soda and phosphate, has the property to produce a fat dissolvingand thereby dirt removing efiect. That'is why it is being used in somany cases as a cleaning agent for all sortsot household and kitchenutensils.

It is further known that the dirt dissolving property of sodiumphosphate will be increased to a certain degree if brought together withthe soaps of ordinary fatty acids or with naphthenic alkaline salt. Andin this combination it is found as one of the ingredients of soaps andwash-powders.

Coming as a surprise it had been found that through the efiect ofsulphuric acid upon fatty oils, the aliphatic sulphonic-acids derived inthis manner as for instance the Turkey-red-oil obtained throughsulphonating of caster-oil, may

be brought into a compound together with sodium or ammonium phosphatewith the result that now this combination will produce materials thatnot only are able to furnish an excellent substitute in many a wayandeveryrespect, but the wetting-out and emulsion power of these bodiestends to go far beyond that of a normal soap.

Example (on. art-5) add50 parts of tri-sodium phosphate slowly and undercontinued stirring. In a comparatively short time the entire mass willsolidify and also form crystals, so that this firm mass is now suit- 5able to be ground and also dissolves in water yielding a clear solution.

Instead of the Turkey-red-oil as mentioned in the above instance we mayalso take another aliphatic sulphonating product as for instance liquidresin treated with sulphuric acid also called Swedish liquid resin-ortalloel. The soda ash may also be replaced with another salt thatis freeof water and which is able to bind water of crystallization to a greateror less degree; and altogether dependent upon the purposes for which thefinal product is to serve, we find that the rational proportions of themixture between sulphonated oils and sodium-phosphates may vary withinwide limits.

It has however also been proven that these bodies first derived mayincrease the emulsive and cleaning power of soaps and soap-likewashing-agents to a far higher degree than if the phosphoric alkaline orammonia salts be added to them individually and by themselves.

1. A detergent comprising approximately twenty-flve parts of Turkey-redoil, twenty-five parts of soda ash, and fifty parts of trisodiumphosphate, said detergent having a high detergent and wetting outproperty.

2. 'The method of producing a detergent which comprises heating togethertwenty-five parts of Turkey-red oil and twenty-five parts of soda ash toform a solution, and slowly adding thereto fifty parts or trisodiumphosphate while continuously agitating the same. I
